List the systemic circulation pathway. Define myocardial ischemia, myocardial infarction, hypoxia, angina pectoris. Discuss the cardiac conduction system. Define each component of the cardiac conduction ystem. Define EKG, define the 3 waves, and discuss the implications of any abnormal EKG wave. Define systole and diastole.
Definition of Cardiac conduction system
• The intrinsic conduction system sets the basic rhythm of the beating heart. • It consists of autorhythmic cardiac cells that initiate and distribute impulses (action potentials) throughout the heart. Page 2. Goals • To identify the components of the intrinsic conduction system.

Determine the complete pathway a drop of blood would take beginning in the superior and inferior vena cava Two events happen in a heart beat. 1. electrical event which causes: 2. muscular event/contraction. Either event can have problems so doctors need the ability to check each one. The Conduction system

Internal cardiac pacemaker. Cardioversion. Muscular event – the Cardiac Cycle. alternate contraction and relaxation of heart. Contractility: innate ability of the cardiac muscle cells to forcefully shorten & cause movement – in response to stimulus from cardiac conduction system. Gives muscle the ability to cause movement. 1.
